What is latency in the context of networking?

The amount of data lost during transmission

The maximum data rate of a link

The time delay for data to travel from source to destination

The actual data rate achieved during a transfer

A network administrator is investigating a user's complaint that downloads are slow. The user's speed test shows 500 Mbps download, but actual downloads from a specific cloud service are only 50 Mbps. The administrator suspects the cloud service is the bottleneck. Which action would best confirm this?

Upgrade the user's internet plan to a higher bandwidth

Run an Iperf test to a server in the same cloud service's data center

Check the user's local network for congestion

Run another speed test to a different server

How does Iperf differ from an internet speed test?

Iperf measures latency only, while speed tests measure throughput.

Iperf is a graphical tool, while speed tests are command-line only.

Iperf measures the bandwidth of your ISP plan, while speed tests measure actual throughput.

Iperf measures throughput between two specific hosts you control, while speed tests use public servers.

When you run an internet speed test, what does the reported 'download speed' represent?

The latency between your device and the test server

The measured throughput for data received from the test server

The speed at which data is sent from your device to the test server

The theoretical maximum bandwidth of your internet plan

A gamer complains that their online game is laggy even though their internet speed test shows high download and upload speeds. The game requires quick response times. Which network characteristic is most likely causing the problem?

Low throughput on the download speed test

Insufficient upload bandwidth for game data

High latency to the game server

Low bandwidth on the internet connection
